TLEBORO, MASSACHUSETTS, A CORPORATION OF RHOIDE HANDLE CONSTRUCTION FOB BRACES AND THE LIKE.

Application filed February 1, 1922.

T 0 all whom it may concern:

Be it known that I, l/VALTER I. TUTTLE, a citizen of the United States, and a resident of Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Handle Construction for Braces and the like, of which the following is a specification.

This invention relates to the construction of handles for braces and the like. One of the objects thereof is to provide a practical construction of the above nature character ized by simplicity and efliciency in action. Another object is toprovide a construction of the above nature in which the parts are 1 securely held in assembled relation andwell adapted to meet the conditions of hard use. Another object is to provide a simple art for forming a construction of the above nature which may be cheaply and rapidly carried on. Other objects will be'in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, arrangement of parts and in the steps and coinbinations'of steps, all as will be illustratively herein described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which the above construction and art are illustratively set forth. 1

- Figure 1 is a plan of a blank for forming a handle member;

Figure 2 is a side view of this blank at a later stage;

Figure 3 is a similar View of the same part at a later stage;

Figure a is a similar view of the same part in its final stage; and

Figure 5 is a sectional elevation of the complete handle and associated parts.

Similar reference characters refer to similar parts throughout the several views of the drawings.

As conducive to a clear understanding of certain features of this invention, it may be noted that thrust handles for braces and similar implements are subject to severe stresses in use and are often exposed to dampness and other unfavorable conditions. Furthermore, if it be attempted to meet the above conditions by ordinary means, there is a tendency to complication and expense.

Serial No. 533,489.

The attainment of a construction which will be essentially simple and inexpensive and which will neverthelesswithstand in an efficient manner the above conditions, is among the dominant aims of this invention.

Referring now in detail to the accompanying drawings, there is first blanked out a piece of sheet metal as shown in Figure 1, this part comprising a body having a plurality of extensions 11 each terminating in a concave recess 12. With the blank in this form it is forced into the condition shown in Figure 2, the body portion 10 being of substantially hemispherical form and the extensions depending, as shown.

In the next step there is formed at the center of the crown of the body portion a depression 13 provided with a central open- In the final step of forming this handle member, the extensions 11 are curved inwardly in such manner as to bring the tip surfaces 12 substantially into a plane and to act as complements of a substantially circular bearing. The side surfaces of the extensions shown at 15 in Figure l of the drawings are in this final form curved as shown at 16 in Figure 4: and the resultant member is thus of a general spherical form, presenting a smooth surface to the hand, and of extremely light construction.

In the next step the shank of the brace or other implement shown in Figure 5 at 17 which is provided with a lug 18 of reduced diameter as indicated in dotted lines, is fitted within the handle member. The lug 18 finds a bearing in the opening 14; and the shank portion 17 likewise has a bearing formed conj ointly by the edges 12 as above described. The projecting lug 18 is thus headed downwardly as shown in full lines at 19 so as to lock the sheet m tal member against the shoulder 20 of the shank 17 and yet permit free rotation thereof.

In the action of the device any tendency of the handle member to tilt is amply met by the two spaced bearings and any tendency to longitudinal displacement of the parts is resisted by the head 19 and shoulder 20. Furthermore, due to the fact that the depression 13 is of a depth greater than the height of the lug head 19, no rotating part comes in contact with the hand of the user. The con struction thus permits comfortable and efscribed might be varied, all without depart- I ing'from' the scope of the invention, it is to be understood that all matter hereln set forth or shown in the accompanying drawings is to be interpreted. as illustrative and not in a limiting sense.

I claim as my invention: 1. The herein described art of forming a handle which consists in shaping a sheet p y v p I that herein ClGSCIlbGCL'lIl combination, aholmetal member into a form with a plurality of outward extensions, forcing said member into an outwardly convex form, and forcing sald extensions inwardly to form a bear ng.

2. The herein described art of forming a' handle which'consists in forcing a sheet metal member mto an outwardly convex form wlth an opening therein, depresslng a portion of said, member and forming an opening in saiddepressed portion, passing another member through said two openings,

and into said depression, and heading over the end of said second member within said depression.

.3. The herein described art of forming a handle which consists in forcing a sheet metal member into a general outwardly con vex form with a pair of openings therein, passing a shank through said openings, each providinga bearing therefor and forming the end of said shank to interlockwith the outer surface bf said sheet metal member.

4:. The herein described art of forming a handle which consists in forming a blank with a plurality of outward extensions, forcing the body of said blankintoan out; wardly convex form, forcing said extensions "inwardly to bring the ends of said extensions into position to form a bearing, passmg a shank member through said bearing and throughfthe opposite side of said sheet I metal member, and locking said shank member inrposition.

5. In construction of the general' nature of that herein described, in combination, a

handle member formed of sheet metal com-J prising a plurality'of separate parts bent inwardly to give a general spherical form to the member, and a second member passing through a wall of sald first'member in a rotary relation thereto, and means holding against relative longitudinal low handle member having on opposite sides a pair of openings and a second member passing through. said openings and having' a bearing in each of the same, and means i I adapted to hold said members against longitudinal movement.

. 7. In construction of the general nature of,

that herein described,in combination, a handie member formed of sheet metal having through and resting in said bearing and se-,

cured for relative rotation to the opposite wall of said handle member.

8. In construction of the general nature of that herein described, in combination, a handle member formed of sheet metal into a general spherical form p-rovidedo-n one side with a depression having an opening through its lower wall and comprising on curved inwardly to form a bearing, and a shank member passing through and restln the other side: a plurality o f-extensions in said bearing an'dpassing through sai opening and headed over within said: depression. i V

In testimony whereof, I; have signed my name to this specification this26th day of- January,1922. l
